FUEL-INLET- VALVE MECHANISM.

vState of 0hio,'have invented certain new and useful Improvements invFuel-. Inlet- Valve4 Mechanism, .'of whi'chthe following is aspecification.

internal combustion motors andl particu'- larly to fuel 'inletl valvemechanism therefor.

More specifically the invention relates to fuel valve mechanism forinternal combustion motors, and it comprises a valve structure includingfuel and air mingling means, a plurality of mixing cups arranged tothoroughly mix and break up the mingled air and fuel, anda discharfvevalve for discharging the mixture into the cylinder.

The invention may be further brieilysummarized as consisting in theconstruction 4and combination of parts, hereinafter set forth in thefollowing description, drawings and claims. f

-Referring to the drawings, Figure 1 is a view of an engine providedWith -my improved valve; Fig. 2 is a vertical sectional view of thevalve structure;'Fig. 3 'is a top plan viewfof the valve structure withthe stuffing box and spring mechanism removed; Fig, -t is a top .planview of the fuel and air mixing device; Fig. 5 is a vertical'sectionthrough the same; F ig. 6 is a top plan view .also p provide of one ofthe mixing cups; and Fig. Tis a sectional view through one ofmthesecups. In carrying out .the invention any pre# ferred form andconstruction of engine may` ossess the necbe employed, provided they7 hp ave s own one essary characteristics, but arraiivement which iseffective, and in such embodiment l represents' the crank case of an'explosive engine provided with a suitable cylinder 2 receivinga piston3, This piston is connected in a manner not shown, by a Iconnecting rod,with the crank shaft which is in the crank case 1, the details of theseparts being unimportant in so far as the invention' is concerned.Mounted upon the crank case is a suitable air pump 4 which is adapted tosupplyair under high compres-v sion to a supply pipe 5. A fuel pump 6`is on 'the crank case and it receives fuel through a suitable pipe 7`and supplies it u'nder highipressure -to apipe 8.`

' The'cylinder 2 is provided with a suitable mannen `"'lihe"foregoing:features are comy p `mon lto. devices of this character and areThisinvention' relates to'fimprovements 1n i onlfy seft forth for thepurpose of forming a-v oundation for any vcombination Iclaims Which-mayappear.

The fuel and air .mixin valve .structure comprises a cylindricalcasin0-.1`2-adaptedto project through the cylinder lhead to ii v.pointnear the combustion chamber'. This casing is provided with diametricallydisposed extensions 13 leach having an opening 14` for al securing bolt.Integral with one of these extensions are suitable connections 15 and16, the former having an opening y17 thereinfor receiving the air 4pipe5,.,the latter having an opening 18 for yreceiving the fuel supply pipe8. The opening 17 communicates with a part 19 formed in the casing alidextending to a central longitudinally disposed opening v20 extendingthrough the casing. Tlieopening 18 in the connection 16 is connected bya port 21 with a longitudinally ing to a mingling chamber 24 formed byen larging the opening'20 in .thecasing At a disposed fuel port 22extending to a point .near the bottom 0f the casing, and there pointcorresponding to the connections 15 and 16, the casing is reducedinternally at 25 for guiding the valve stem, as will later 'appear, andabovethis' point the casing is provided with a stuffing box extension 26externally threaded landhaving an enlarged opening 2 7 for, receivinpacking 28, which is engaged by a glanc 2.9 held vin place, by "a glandnut 30 provided with a flan e 31 receivin the thrust of a spring 32. helower end o the casing-is enlarged-at 33 over the chamber 24 to receivethe threaded sliankv35 of a plug36. This pliig is bored out to vforma-mixing chamber 37 and is again reduced by a tapering portion 38 to adischarge openingL39-liaving -a valve seat 40 at the outer -r edge.`Coperating Withthis valve seat is a valve 41 carried by a valve shank 42preferably lintegralwith the valve stem-43 which are, through throughthe packing 28 and out at the top where it has an annular roove 43receiving a split collar 44 adapte to engage in a. tapered opening 45`in a sprin Washer 46 adapted to receive the upper spring 32. Thisstructure is common in devices of this sort. f

Within the mixing chamber 37 in the plug 36, the stem 43 is providedwith a plurality of mixing cu s comprising a cylindrical portion 4 an abottom Bange 48 which is rovided with a plurality of minute openings 49and a-centralopening 50 for receiving the stem 43. There is a pluralityof these cups, as stated, and they are suicient in height when arrangedone upon the other to occupy the mixing chamber 47 and they are held inplace b a mingling block 51 which is provided with a central opening 52larger than the valve stem 43 and correspending in bore to the bore ofthe opening 20, thus permitting the continuance of the flow of airthrough the opening 20 about the valve stem. This block isl providedperipherally with an annular groove 53 at a oint in alinement with theport 23, and this recess communicates by diagonally disposed inwardlyextending. ports 54 with the cen tral opening in the block, so that thefuel which enters through the ports '2Q and 23 passes into the annulargroove 53 and is thence distributed through the diagonal ports 54 in aseries of streams to the air, the mingled fuel and air then passing fromone mixing cup to the other and finally en tering the chamber 39, fromwhence at the proper time it is discharged through the valve into thecylinder.

Havin described my inventiomlclaim- 1. .A4 uel and air mixing valvestructure comprising a casing having a discharge, a longitudinallydisposed opening therein forming an air supply port, a fuel supply ortextending from the outside of the casing to a .point near thedischargeend of said casing and communicating with the air supply port, a fueland air mingling block arranged in-,the air supply port andcommunicating therewith, and also communicating with the fuel supply, adischarge plug arranged in the end of said casing Vadapted to hold saidmingling block in place and provided vwith a p urality of mixingcupsarranged .in said plug and eachV having a plurality of minute openingsin the t irust lof the f bottom, a dischaige valve arranged in said`plug, and means or actuating said valve.

2. A fuel and air mixing valve structure comprisin a casing having adischarge, a longitu inally disposed opening therein forming an airsupplyl port, 'a fuel supply port extending from t e outside of thecasing to a point near the discharge end of said casing andcommunicating with the air supply port, a fuel and air minglin blockarranged in the air supply ortA an communieating therewith andA a socommunicating with the fuel su ply, a discharge plug arranged inthe enof said casing adapted to hold said mingling block in lace and providedwith a plurality of mixing cups arranged in said plug and each having aplurality of minute openings in the bottom, a discharge valve arrangedin said plug2 and a valve stem extending through the ,mixing cups,through the mingling block and the casin for actuating said valve.

3. fuel and air mixing valve structure comprising a casing having acentral longitudinall disposed opening for the passage of airl or avalve stem and terminating at the lower end in a mingling chamber, afuel supply openingv extending longitudinally through the casin andcommunicating with the mingling c iamber, a mingling block arranged inthe mingling chamber and provided with an annular recess for receivingfuel from the fuel supply port and diagonally disposed openings forsupplying fuel to the centrally disposed opening in said block, a plugin the lower end of said casing and having a mixing chamber and adischarge opening7 a plurality of mixin kcups 4arranged in said mixingchamber, an each comprising a cylindrical portion and a bottom flangeprovided with minute openings and a centrally disposed opening, adischarge valve for controlling the discharge through the centrallydisposed opening in.

said mixin cups, through the opening in said mingling block, through theair supV ply opening, and out through the top of the casing.

In testimony whereof I affix my signature in presence of two witnessesas follows.
